Description

The SPMD150STP is a highly integrated stepper

motor driver module, that allows the user to easily

design a complete motor control system for two-

phase bipolar stepper motors, interfacing directly

the microprocessor to the motor.

The SPMD150STP is an easy-to-use fully

integrated answer to motion control issues.

The phase current is chopper controlled, allowing

good performances and high speed.

Modules offer an extensive range of protection

such as overcurrent and thermal shut-down, that

make it “bullet” proof as required in modern

motion control systems.

Metallic case allows module to operate without

external heat-sink or ventilation; moreover the

sealed and molded package offers a complete

protection against harsh environments.
